Title: Recording seismic exploration data
IPC: G01V1/24
Filed: 1970-04-13
Abstract: 1308033 Seismic exploration TEXAS INSTRUMENTS Inc 13 April 1970 [16 April 1969] 17445/70 Heading H4D In a system for recording reflections of seismic disturbances produced by a source, the interval between generation of a disturbance and the arrival of useful reflections at seismic detectors remote from the source is used to record in separate recording channels the outputs (shallow reflection signals) of seismic detectors nearer the source, these channels being used subsequently to record the useful reflection outputs of the remote detectors. In the embodiment shown an array of, e.g. four closely-spaced detectors 12a-12d provides the shallow reflection signals and an array of, e.g. twenty-four more widely spaced detectors 14a-14x provides deep reflection signals. A twenty-four channel recorder 18 (digital or analogue) has twenty of its channels allocated to detectors 14a-14t and its remaining four channels 32a-32d are connected first to detectors 12a-12d and then, when useful deep reflections are expected, are switched (sequentially or simultaneously) to the most remote detectors 14u- 14x. The switching may occur a given time after the seismic disturbance generation or, in an alternative embodiment (Fig. 4, not shown) may occur in response to useful signals being detected in the recording channels of the detectors immediately preceding the most remote detectors. A programmed gain control system 22 (which may be part of the recorder) provides greater amplification for the deep reflections than for the shallow reflections. Wide passband and narrower pass-band filtering may be applied to the shallow reflections (containing high frequency components) and deep reflections (comprising lower frequencies) respectively.

Title: Improvements in or relating to television systems
IPC: H03K4/26
Filed: 1932-06-27
Abstract: 387,915. Television. RADIO CORPORATION OF AMERICA, 233, Broadway, New York, U.S.A.-(Assignees of Tolson, W. A. ; 631, Jefferson Avenue, Erlton, New Jersey, U.S.A.) June 27, 1932, No. 18165. Convention date, June 25, 1931. [Class 40 (iii).] In a television or like system independent line-scanning and picture-framing operations at the receiver are synchronized with the corresponding operations at the transmitter by means of a single series of signals of the picture-framing frequency generated at the transmitting station. In the arrangement shown each synchronizing signal consists of a short duration wave, say, of 30 kilo-cycles frequency, transmitted once during each revolution of the Nipkow disc or equivalent element 14, Fig. 1, the disc being fitted with a projection 13 that is adapted, in the interval between successive image transmissions, to close a switch 12 controlling an oscillator 10 of the selected frequency, the length of the projection 13 determining the duration of the signal. At the receiver a valve 32, Fig. 3, the anode circuit of which is tuned to the frequency of the oscillator 10, co-operates with a radio receiver and resistances 16, 17 to separate the synchronizing waves from the picture currents. The latter are passed to the control grid 21 of a cathode-ray tube 22, while the synchronizing waves, after rectification by a valve 34, and consequent conversion to unidirectional impulses of the picture-framing frequency, are passed to two control apparatus 30, 27 which are associated respectively with coils 28 and plates 25 of the cathode-ray tube 22 so as to regulate the vertical and horizontal deflections of the ray 23. The apparatus 30 includes means, Fig. 5 (not shown), for delivering to the coils 28 a saw-tooth potential and comprises a source of high potential, a high resistance, and a condenser on which a charge is gradually built up until the potential reaches the breakdown voltage of a triode arranged in parallel with the condenser, the discharge occurring at the picture-framing frequency by applying to the grid of the triode via connections 36, 37, Fig. 3, the impulses delivered by valve 34. The apparatus 27 also includes means, Fig. 6 (not shown), for delivering a sawtooth potential to the plates 25, the discharge of a condenser at the line scanning frequency being effected by a dynatron oscillator of adjustable frequency tuned approximately to the line-scanning frequency, this adjustment being carried out initially to a point where only a slow drift of the received picture on the screen 24 of the cathode-ray tube is observable. With such an initial adjustment the line-scanning oscillations of the transmitting and receiving apparatus are sufficiently close in phase to be brought into exact synchronism by the impulses of lesser frequency delivered from the valve 34. Other forms of oscillators may be employed in the apparatus 30, 27.

Title: Improvements in or relating to the coating of reticulated foam structures
IPC: C08J9/40
Filed: 1965-04-29
Abstract: Solid particulate material is deposited on a reticulated organic, polymeric foam material by temporarily attaching said particulate material on the strands and nexae of said reticulated material by intimately dispersing said particulate material throughout the organic body, and subjecting the organic material covered with the particulate material to an explosive frame front, and if desired repeating said steps.  Foam materials mentioned are: polyurethanes such as polyether, polyester, polycarbonate, castor oil polyurethanes; polyvinyl foams such as polyvinyl chloride, acetate, and vinyl copolymers.  The foam substrate may be coated with materials such as polyolefin prior to the deposition of particulate material e.g. polyurethane foams coated with polyethylene.  The particulate material may be: inorganic material such as powders of iron, bronze, aluminium, copper, nickel, platinum, titanium, berylium, and mixtures of these powders, mixtures of nickel and platinum, complexes of titanium and vanadium, charcoal, graphite, titanium oxide, alumina, kieselguhr, asbestos, glass, mineral material such as silicone oxides or silicaceous base materials; organic polymers having melting points above the melting point of the foam material e.g. nylon, Teflon (Trade Mark), Kel-F (Trade Mark) and the higher melting polymers of 1-olefins such as 1-butenes.  The particulate material may be temporarily attached to the foam structure using water, or, if the foam is hydrophobic, volatile organic solvents such as ethyl alcohol and benzene, or fluids possessing small contact angles with the foam and particulate materials.  The explosive flame front may be created by permeating the reticulated foam material with an explodable fuel gas or explodable liquid and a gas containing an explosion-sustaining amount of oxygen, and igniting the gas mixture.  Various layers of materials may be deposited to form say catalytically active contacting pads, adsorbents for removing impurities from fluid streams, electrostatic filters, an absorber for high frequency electromagnetic energy. Conductive particulate materials are suitable for improving thermal emissivity and electrical conductivity.  In the Examples graphite powder is deposited on a reticulated adipate polyester polyurethane foam, and nickel powder on a reticulated polyether polyurethane foam.
